Question 786086: Find the equation for an exponential function that passes through the pair of points given below.

F(X)= Answer by xinxin(76) (Show Source):
You can put this solution on YOUR website! The basic expression for exponential function is F(x) = aK^x, plug in the numbers:
aK^(-2)=5
aK^3 = 3
From the first equation, substitute a with K: a = 5/K^(-2). Combine this with the second equation:5/K^(-2)*K^3 =3
Solve for K, get K = 5th root of 3/5 = 0.9, a = 4.1
